A Canopy

1. A high cover providing shelter, such as a cloth supported above an object, particularly over a bed.
2. Any overhanging or projecting roof structure, typically over entrances or doors.
3. The zone of the highest foliage and branches of a forest.
4. In an airplane, the transparent cockpit cover.
5. In a parachute, the cloth that fills with air and thus limits the falling speed.
